Introduction to Voltronics Corporation
Voltronics has been supplying high performance multi-turn trimmers
since 1963. Our range of trimmers are suitable for applications that
require high precision, mechanically stable with a high tolerance
to vibration and shock. Our success is based on a unique sealed,
non-rotating piston design that has become one of the designers
preferred choices for demanding applications.
As well as our extensive range of standard products we are able
to design and manufacture customized products for our specialty
customers. In addition we are able to offer a range of half turn
trimmers suitable for less stringent applications, but still providing
good stability and voltage handling capabilities.
For more than 30 years Voltronics has been partnered with leading
MRI manufacturers, supporting them with the highest quality
non-magnetic components. This has grown from just supplying
trimmer capacitors to now include a broad offering of non-magnetic
components focussed on MRI applications.

Washing Instructions:
The J-Series trimmer capacitors can withstand cleaning cycles up to 10 PSI and have been used by customers for more than a decade in
many diverse environmental conditions. Without knowing your particular washing or cleaning environment, we
recommend these basic guidelines:
:DWHUZDVKRULVRSURS\ODOFRKROFOHDQLQJDJHQWVDUHDFFHSWDEOHSURYLGLQJWKDWEDWKVDUHFOHDQDQGXQFRQWDPLQDWHG
For maximum effectiveness, the cleaning process should occur immediately after soldering.

$OVRZHGRUHFRPPHQGWXUQLQJWKHWXQLQJVFUHZRUFRPSOHWHUHYROXWLRQVSULRUWRDUULYLQJDWWKH¿QDO³VHW´
* If a water wash process is used and water does get inside, we recommend that the parts be heated above 100C for a minimum of 15
minutes, so that the water evaporates. After this, the rotor should be turned 1-2 times to redistribute the internal grease.

A_HV & E_HV - High Voltage PTFE Trimmer Capacitors
The Only Internally-Sealed HV PTFE Trimmers
Voltronics’ concentric ring PTFE dielectric trimmer capacitors are
designed for use at frequencies up to 1.5 GHz. They are ideal
for HIGH VOLTAGE applications. The solid internal PTFE dielectric
prevents ionization, a major advantage in space, high altitude and
high voltage applications. The unique internal O-ring seal makes
wave soldering and vapor degreasing possible without the need to
attach a separate cap.
